TL;DR: This review deals with the consistency of the genomic positions of quantitative trait loci (QTL) controlling resistance across different maize populations, and with the clustering of genes for resistance to S. turcica and other fungal pathogens or insect pests in the maize genome.

TL;DR: The observed entry x country interaction for ASVPC may be due to the entries' different reactions to climatic conditions and putative differences in striga virulence in Mali and Kenya.

TL;DR: A combined sorghum linkage map from two recombinant inbred populations was constructed using AFLP, SSR, RFLP and RAPD markers, in good agreement with other sorghums linkage maps, from which it deviated by a few apparent inversions, deletions, and additional distal regions.

TL;DR: Bimodal frequency distributions supported the hypothesis of one recessive gene with a major effect for low maximal germination distance in progenies from crosses of low-stimulant lines with a high- Stimulant line, tested with striga from Mali or Niger, however, low- versus high-stimULant classes were not always clearly distinct, indicating that additional minor genes modified maximal gerulation distance in the progenie.

TL;DR: The agar-gel assay proved to be a useful, precise and fast indirect selection method to screen for sorghum entries with the low-stimulant character, but correlation analysis showed that this resistance mechanism was ineffective in some environments, especially in Kenya, pointing to the necessity of field evaluation.
